SenseFind

At the present time TreeStages has finished development of SenseFind, a lexical navigator application.which can be downloaded from our web site: Download SenseFind

This simple application supports:

- text editing as well as dispalying meanings and reading of english words in the text

- fast lexical browsing of dictionaries

- monitoring of selected words in other applications and displaying their dictionary description

- TTS reading of selected items and text audio recording.

XEntrant

Couple of years ago TreeStages developed first version of XEntrant, a model driven XML editing application.which can be downloaded from our web site: Download XEntrant

XEntrant is an XML editor supporting editing and validating of:

- XML documents instances (wellformed or predefined)

- DTDs (document type definitions)

- XML Schemas

- XSL Transformations (Extensible Stylesheet Language)

What are other benefits for the user?

Simple and easy work with nodes and subtrees only, instead of with tags and complex structures in a text form.

There is no need to remember syntax or structure of definitions. At any point in time while editing you can not only see definitions and types of edited nodes but you can drag and drop individual items from the definitions into any location within the instance document allowed by another powerful feature - prevalidation.

All of the above allows to accelerate relevant applications development time substantially and to benefit increasingly from the generic features of XML design.

Improving and speeding up XML learning process.

We certainly know what we are talking about because besides other applications many components of XEntrant itself, its infrastructure, metadata and documentation, as well as these web pages were designed and developed by using it extensively.

Misc...

This web site (let alone XEntrant itself) is a representative implementation how XEntrant XML design technology can be applied. All its pages were generated by MS XSL Transformation engine from documents created with our software.

Another obvious example of our extensive use of XEntrant is MS Windows HTML-help package for XEntrant which was generated by our XML Documentation Plugin - Download Help

How convenient it can be to generate web pages using XEntrant and XSL Transformations is demonstrated also on the examples of income tax form pages in the section - Examples

About Us

TreeStages developers are primarily interested in providing user friendly XML, DTD, XSL Transformation and XSD Schema editing, validating and metadata processing tools with plugins. Our software XEntrant is easy to use and offers the whole range of convenient editing, validating, browsing and searching features compliant as much as was possible with W3C standards and relevant for a broad spectrum of software development.

The other application we have been working on recently on is our new software SenseFind. It is a simple dictionary browser and text editor featuring also TTS reading, recording of audio output and monitoring of words or text segments selected in other applications with instant displaying of their dictionary meanings. Originally we developed this tool for ourselves to enhance our skills and abilities in English. After using it for some time we think it might be useful for many people learning English (and later on maybe even for other languages).

Goals

To provide the software development enhancing tools (mainly for XML applications) and natural language processing tools.

With user friendly browsing and object modelling features to alleviate complexity of W3C standards, to make them more attractive and enable users to move up the learning curve considerably faster.

To focus on the group of application developers and web designers who like us are not good in remembering cryptic details of standards, but could still benefit from XML technologies.

And in the recent time to make accessible interactive tools for navigating through dictionaries and thus shortening the language learning curve.

With our language tools to focus on the group of people who like us are not good at learning foreign languages.

To improve the performance and features of our software in the future, and to make it more standard-like.

Technology

The main field of interest for TreeStages are software development enhancing tools as well as natural language processing tools with the focus on XML applications. To be more specific our software XEntrant is an implementation of XML tree editing tools. The intuitive and user friendly interfaces of all our software has been developed using the Python programming language, its libraries and interfaces, which are freely available for public.

SenseFind ScreenShots

The main window of the SenseFind application GUI:




The following picture demonstrates the use of the SenseFind event monitoring and balloons in interaction with an internet browser.




XEntrant ScreenShots

To illustrate some of our XEntrant software functionalities and features we are including the following screenshots:



Templates




Templates represent a convenient user friendly way for creating and editing repetitive document subtrees, of which element structure remains unchanged and only the text nodes can be reedited. In essence, templates are forms with structures determined by a subtree of elements and users can fill them out.

You can edit text in editable fields of the template and replace corresponding subtree in the document or insert the subtree before/after the selected node.

Editable text fields in a template can be stretched or shrank to an appropriate size by pressing the right mouse button and moving the mouse pointer. Attribute text fields can be stretched only in horizontal direction.

If the allowed values of the text field are from an enumeration set the possibility to use dropdown menus is indicated by a black arrow on the right side of the text field. Edited values are validated on the fly.



UBL Order Templates

This example shows templates for UBL (Universal Business Language) Order 1.0 XML instances. Corresponding UBL standard XML and XSD files can be found at: OASIS UBL Site

XSL Transformations




Implicit model for XSLT instances displayed in the right top subwindow allows us to use an efficient drag and drop operation for editing XSL documents in addition to easy model browsing.



XML Schemas




Implicit model for XSD documents displayed in the right top subwindow allows browsing and the use of efficient drag and drop operations for editing XML Schema documents.



DTD Documents




DTD document tree declarations can be recursively browsed and edited in the instance frame (left subwindow). Declaration meta type model trees can be viewed and browsed within the type frame (right top subwindow) representing type models of selected instance tree nodes. Drag and drop operations can be used for creating and editing element declarations in the current declaration context.



Plain Text Tagging




To create an XML document from plain text one has to at first paste the text as a character data under the root element. The root element should be then selected and the text frame should be switched into a tagging mode.




To tag the text the chosen elements should be drag-and-dropped or copy-pasted into the text. To encapsulate the text area (mixed with previously created elements) following the dropped element, the user has to highlight the text and tags to be contained in the new element and the "Include Selected" option should be chosen from the frame popup menu.




The final result of tagging could look like this. In this way it is possible to tag a page of text in few minutes.



Image Map Hot-Spots




It illustrates a convenient feature for displaying an image in the top right frame of the application window and allowing the user to drag and drop coordinates or hot-spots (sets of coordinate points) into data nodes in the instance tree. The specific type of image and coordinates (absolute or relative) can be selected.

XEntrant XML Editor

XEntrant is a model driven XML editor supporting editing, browsing and validating of:

- XML document instances (wellformed or predefined)

- DTDs (document type definitions)

- XML Schemas

- XSL Transformations (Extensible Stylesheet Language)

Benefits

Simple and easy work with nodes and subtrees only, instead of with tags and complex structures in a text form.

There is no need to remember syntax or structure of definitions. At any point in time while editing you can not only see definitions and types of edited nodes but you can drag and drop individual items from the definitions and instances into any location within the instance document allowed by another useful feature - prevalidation.

In the case of documents with XML schemas the type definition models in the top right model window are results of type inheritance hierarchy merging from all included / imported schemas.

Improving and speeding up XML learning process.

Components

The main components of the XEntrant application GUI include three frames, the horizontal menubar at the top, the vertical toolbar on the left, and at the bottom the status line and the node number indicator.

The Instance Frame on the left is used for browsing and editing XML document instances, DTDs and schemas.

The Type Frame at the top-right of the application window displays the model types related to the selected nodes in the Instance Frame.

The bottom Data Frame on the right is used for editing the instance frame selected node text or its children tags mixed with text.

Most of the user interface control over the various browsing, editing, parsing and validating operations is provided by the main menubar menus, the toolbar buttons and the pop-up menus on all three frames. The status line shows messages indicating the status and results of parsing, editing and validating operations.




Features

The editing functions include various user friendly features pertaining to individual nodes and specific to the application window frames:

- editing of XML document instances

- editing of DTDs

- editing XML Schemas

- editing of XSL Transformations

Getting Started

To learn the basics about the SenseFind application see the video tutorial: SenseFind Introduction

This tutorial is in the section Getting Started with SenseFind.

Download

A fully functional evaluation version of SenseFind with a 1000-day trial period is now available for download.

SenseFind software can be downloaded as self-extracting executable files:

The application itself - Download SenseFind

Download SenseFind - Lexical Navigator

The SenseFind installation package can be downloaded by clicking on the DOWNLOAD button. The downloaded file is a selfextracting Windows executable installation package.

If you already have SenseFind installed and you want to reinstall it in the same directory you should execute the uninstall first.

For some applications (Internet Exporer, Notepad, Wordpad, ...) the direct text selection monitoring is implemented using Windows Accessibility Interfaces. Other applications (Firefox, Adobe AcroRd32, ...) can be monitored by sending the "Copy" command to the active application. This will copy the selected text into the System Clipboard. In SenseFind it can be achieved by adding the name of the application executable (which can be seen in the Windows Task Manager list of running processes) into the file Mon_Apps.txt.

WARNING: Changing the content of the System Clipboard during the execution of some applications can cause significant side effects in the behaviour and results of application specific operations, commands and features (not only the simple text editing Copy & Paste, but nontransparent, complex object manipulations in particular). Therefore, one has to be very careful and aware of what he/she is doing when changing the content of the Mon_Apps.txt file. While Monitoring is enabled those applications should be used only for viewing their content. If the user wants to do some content modifications in his application the SenseFind Monitoring should be disabled first to prevent the failure of usual Copy & Paste mechanism.

Getting Started with SenseFind

To learn the basics about the SenseFind application follow the link to watch the video tutorial: SenseFind Introduction

Getting Started with XEntrant

To start building a new document click the File Menu and select the New-> XML submenu option. This will open the new file with the name "Untitled. xml" or some derivation of this name (with generated numerical extension) if it already exists.




In the main application window you can see besides the menu, tool and status bars the three frame windows.

On the left hand side it is the Instance Frame now showing just the root node of the xml document instance tree with the label "DOCUMENT".

On the right hand side it is the Type Frame at the top with the type definition tree of the selected root instance node, and the Data Frame at the bottom with the text of the selected node label. In the Help Menu choose Node_Help -> General_Info_On. This will show popup balloons with the information about nodes pointed at by the mouse. These balloons will tell you which of the nodes on the right side are expandable and which are draggable. Try to expand type definitions of some of those nodes and browse definitions using right mouse button and Back or Forward popup menu items.

Click the DOCUMENT node on the left side, the type model on the right side will show components of its possible content. Expand the ROOT_ELEMENT node in the Type Frame by double-clicking it.

Select the node "#WELL_FORMED_ELEMENT", press the right mouse button and drag the mouse pointer to the left Instance Frame root node until the pointer changes to the right arrow and the popup balloon with the sign "Child" appears. Then release the right mouse button. This will open a new editable node under the root. Type the text "EBook" into the new node and press the Return Key. The white editable node changes to a new element node with the name "EBook".




In the same way create the element "Title". The elements "Author" and "Chapter" as siblings of the element "Title" create by dragging the mouse pointer to the left Instance Frame element node until the pointer changes to the down arrow and the popup balloon with the sign "After" appears.




Click on the following objects in this order: the element node "Title", the toolbar "Copy" button, the element node "Chapter" and the toolbar " Paste Child" button. Another instance of the element node "Title" appears, this time under the node "Chapter".




The same effect can be achieved in other ways. One of them is dragging the copy of the first "Title" node to the new location. Click on the toolbar " Undo" button, which should remove the newly created "Title" node. Then move the mouse pointer over the first "Title" node, press the right mouse button and drag the mouse pointer to the "Chapter" node where you drop it as a child node releasing the right mouse button when the balloon "Child" appears.

Now drag the ATTLIST node from the #WELL_FORMED_ELEMENT model on the right side Type Frame to the Author element instance node on the left side and drop it as its child. Then in the same way drop the #WELL_FORMED_ATTRIBUTE node under the new ATTLIST node, type in the text "Name" and hit the Return Key. Double-click the node ATTR_VALUE on the right side, and drag the node CDATA to the left dropping it as a child of the attribute "Name". Type in the text "John Smith" and hit the Return Key.




Now drag the #WELL_FORMED_ELEMENT node from the right to the "EBook" element instance node on the left, and drop it when the popup balloon shows the text "Parent" above the top-left corner of the "EBook" node. Type "EBookList" into the new parent node and hit the Return Key.

Click on the "EBook" node; drag it and drop it as another child of the "EBookList" node. The same effect can be achieved by using the Copy, Paste Child or Paste Before / After menu items or toolbar buttons. Try it after clicking the Undo button.

Expand the new "EBook" node subtree by double clicking or using "Expand All", click the author's name attribute data node, press the Return Key and retype the name "John Smith" with the text "Peter Heller". The resulting tree should look like this:




You can save your work by selecting the File -> Save As Menu Item and typing the name of the file (for example: "ebooklist. xml").

In similar manner other element, attribute and data nodes can be created.
